True ending:
Successfully complete the game with the best ending to get the Channeling Stone. You have to use this item in five different locations to get the true secret ending:

1. On the roof of the "Alternate School".
2. In the hotel parking lot. 
3. The cabin of the boat.
4. Outside the entrance of the "Alternate Hospital". 
5. On top of the lighthouse.

The first four can be done in any order, however use the stone as soon as you enter those locations. The fifth location must be the last place you use the stone.

UFO ending:
Use the Channeling Stone that you obtained at the convenience store. You will find out that you have been summoning aliens all along. They will converge at the lighthouse and take you to their leader. It is not the best ending, but you will be treated to a humorous sequence and you will get the hyperblaster at the start of your next game using your gold saved game.
